Troytest 5-Bottle Precious Metal Testing

Five-bottle tester designed for comprehensive precious metal analysis. Tests all carats of gold and silver (as per the QUICKTEST-3), includes a fourth bottle for white metals (as in the 4-bottle TROYTEST), and a fifth bottle for identifying low-carat gold (5ct–8ct) and 9ct gold with high zinc content.

Each testing acid reacts with the metal, producing a distinct colour change and reaction speed that clearly indicates the metal type.
